摘要
介绍了环氧树脂浸纸电容式变压器套管模拟地震振动台试验。套管通过刚性支架固定于振动台面上,试验中进行了白噪声动态特性扫频及人工波抗震性能测试,评价了其整体抗震性能。试验结果表明:当法兰处三正交方向测点加速度幅值近似为1. 0g时,套管根部法兰最大实测应力为32. 84MPa,最小安全系数为2. 44,结果满足套管抗震要求。
In this paper,a simulated seismic shake-table test of resin impregnated paper condenser bushing is introduced. The bushing is fixed on the table by the rigid support. In order to evaluate seismic performance of the bushing,the white noise dynamic sweep and artificial wave seismic tests are carried out. The results show that: while measuring point acceleration amplitudes of flange are about1. 0 g in three orthogonal directions,the maximum measured stress of the bushing flange is 32. 84 MPa,the minimum safety coefficient of the bushing is 2. 44. The results meet seismic requirements of the bushing.
